Re: [Numpy-discussion] memmap working?
Not sure. When I run top I see the line Memory: 6016M real, 2895M free, 4174M swap in use, 2427M swap free Its the second number that drops like a rock. Plus, it never comes back until I quit the program. This is a great way to turn my machine into a nice desk ornament!
